2 Claims.

This invention relates to a novel automatically operating window screening device.

One of the main objects of this invention is to provide a window screening device which is auto- 5 matically operated by the opening of the window, so as to extend across the window opening for properly screening the same; and which is again automatically retracted by the closing of the window. lo Another object of this invention is to provide such a screening device which is compact and durable in construction, and is efiicient in use, and which at the same time presents a neat appearance. These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing in which this invention is illustrated in its preferred .form of construction; it being understood that various other arrangements and forms of construction may be resorted to for carrying out theobjects and purposes of this invention.

In the drawing:

Fig. 1 is an elevational view of the device, parts being in section and parts being broken away, and v Fig. 2 is a partial perspective view of the screen roll.

In the drawing my invention is illustrated in its preferred form of construction, and it is herein shown mounted between the lower parts of the side frame members or jambs ll of the window frame, adjacent the lower frame member or win- 35 dow sill l2, for screening the lower window opening. This device can likewise be applied to the upper window sash for screening the upper window opening.

This device comprises a cylindrical roll I1, 10 which preferably includes an outer member [8 and an inner member 19 telescoped therein, to enable adjusting the roll to the desired length. The roll is slitted longitudinally. and the screen 2! has its end part inserted in the slit and secured in position. This is preferably done by means of a curved doubled member 22 which has the screen enter thru its mouth portion outside of the roll and extend into its toe portion 22 in edge of the roll, thereby securely clamping the screen edge therein, as indicated in the drawing. The two parts [8 and IQ of the roll are readily telescoped together .and slid upon member 22 with the screen therein, being thus adapted to fit side of the roll, while a heel 22" bears under the screens of various widths, and also to prevent the one roll part from turning on the other.

The means provided for rotating the screen roll in the window frame comprises a pair of axle means 23, one positioned at each end of the roll, and a washer 24 secured in each end of the roll, adapted to rotate on the axle means 23. Said means 23 includes an axle portion or neck 25 Whereon the washer rotates having an integral flange 26 at the inner end thereof engaging against the inner side of the washer. A head plate 2? is fastened removably to the outer side of portion 25, as by suitable screws; and a rectangular post 29 extends outwardly from said head plate and is mounted in a rectangular portion 3B of a bracket 3| which is secured to the jamb II. The bracket 32 at the other side of the roll may be similar in construction or may be in the form of a disc secured to jamb' H and having a rectangular opening therein to receive the opposite post 253 of the roll to hold the axle members against turning. A stem 33 extends inwardly from axle portion 25, and carries a coil spring 34 thereon which has one end secured to the stem and has the other end secured to the roll, whereby this spring is coiled tighter on the stem as the screen is unrolled with the opening of the window. The head plate 2'! is detachable from axle portion 25 for the purpose of assembling the members.

The free end of the screen is suitably attached to the adjacent bar of the window sash to travel therewith.

The two side edge portions of the screen travel in guide channels 40 mounted on jambs l I, closely adjacent the window sash.

Means is provided to cover the space between the sill I2, and the roll when unwound, and this means includes a guide roller 43 which is positioned closely adjacent to sill l2 and has end pins rotatably mounted in bearing means 44 secured to jambs II. The screen 2| thus passes from the screen roll under this guide roller and then upwardly, so that it will always be held closely adjacent to sill 12 when the screen roll is unwound as well as when it is wound.

I claim:

1. A window screening device mountable in a window frame, said device comprising a screen and a roller containing two telescoping portions adjustable for length and slitted longitudinally, and a doubled strip clamped over one end of the screen and together therewith extending thru the slit, said strip including oppositely extending means engaging the interior of the roller adjacent the slit and holding the strip and screen securely inposition. i

2. A window screening device mountable in a I window frame, said device comprising a screen and a roller consisting of two telescoping cylindrical portions clamped tightly together but beingseparable and adjustable for length and provided with a longitudinal slit, and a curved doubled strip clamped over one end of the screen and together therewith extending thru the slit, said strip including oppositely projecting toe and. heel portions engaging the interior marginal portlions of the roller alongside the slit, to held the strip andscreen securely in position therein.
